Key Features

Proven Cummins B Series Reliability: The QSB6.7 is based on the B Series engine platform. It features a robust parent bore cylinder block designed for reduced noise and increased durability.
High-Pressure Common Rail Fuel System: The engine uses a high-pressure common rail fuel system that delivers injection pressure up to 1600 bar. This provides precise fuel delivery, improved performance, and better fuel efficiency at every rpm.
Turbocharged and Charge Air Cooled: The wastegated turbocharger provides better low-speed performance and high-speed boost. The charge air cooler reduces intake air temperature for more efficient combustion.
Multiple Emission Configurations: Depending on the variant, the QSB6.7 meets Tier 3, Tier 4 Interim, Tier 4 Final, EU Stage IIIA, Stage IV, or Stage V standards.
Quiet Operation: The engine is quieter in operation than its predecessor. The rear gear train design significantly lowers noise output.
Improved Cold-Start Capability: The QSB6.7 has improved cold-start capability, making it suitable for operation in colder climates.
Electronic Engine Control: The engine combines full-authority electronic controls with the reliable performance of the B Series design.
In-Cylinder Combustion Technology: The engine meets emissions standards without external components on Tier 3 versions. It is compatible with high-sulfur fuels for worldwide use.
Fully Rebuilt to OEM Standards: We completely disassemble each engine and rebuild it to original Cummins factory specifications. We recondition the cylinder head and inspect the cylinder block. We service the fuel injection system and turbocharger. All critical wear parts are replaced with new components.
